3 MEDICAL LASER SYSTEMS LASER TECHNOLOGY On a daily basis doctors all over the world undertake thousands of laser treatments to efficiently deal with medical, cosmetology, and aesthetic challenges. Since 1960, when the laser phenomenon was discovered, the technology has constantly advanced to transform it into routine and safe application. The efficiency and high technology nature of lasers drive their presence in our life on a bigger and bigger scale. In particular, aesthetic medicine, dermatology and cosmetology have become those areas which cannot be imagined without laser technologies anymore. A laser with certain parameters is capable to incise and prosect tissues, as well as remove and coagulate malformations, and treat developments and anomalies of intradermal vessel. At the same time application of laser provides for relative ease of use, low traumas and high selectivity of effect. Laser emission features a number of specific characteristics that define how and at what depth biological tissue is affected. Depending on a wavelength the laser targets various substances within human skin, that can either reflect or absorb laser emission, such as water, hemoglobin, melanin, oxyhemoglobin. The latter ones, according to a known theory of selective photothermolysis, are chromophores, that is components that selectively absorb laser energy. For instance, since green KTP laser (532nm) penetrates through upper skin layers and is well absorbed by hemoglobin, it is widely used for vascular lesion removal. As a result, the affected vessel undergoes intense emission of heat, the blood clots, and the internal vascular wall deteriorates. The vicious vessel then heals with connective tissue, and the skin color returns back to natural. You can check how well each chromophore can absorb laser emission depending on a wavelength on a graph below.

4 MAGIC MAX A three-wave medical laser for gynecology and aesthetic medicine. 532 nm 808 nm 1064 nm Nd: YAG+KTP Diode Nd: YAG The MAGIC MAX provides for application of various modes within a single procedure by switching between the wavelengths in seconds, which makes it universal for a wide range of medical applications. The diode-pumping technology eliminates any flash lamps in the laser systems, and therefore is not subject to cumbersome and expensive aftersales service. Application: OTORHINOLARYNGOLOGY removal of polyps, coagulation of Kiesselbach s area vessels, OSAHS (obstructive sleep apnea hypopnea syndrome), rhonchopathy, tonsillectomy, adenoidectomy, nasal septum correction. Laser surgery in ENT secures best attenuated treatments of mucous coat of pharyngeal and nasal cavities, and thus saves extremely valuable functions of epithelial and adenoid tissues. REMOVAL OF VASCULAR LESIONS (including child malformations) at various depths (telangiectasia, Rosacea, hemangiomas, wine stains). The mechanism of action is based on selective absorption of laser energy by oxy- and ferrihemoglobin, as well as by protein structures responsible for blood clotting process. Through the absorption of laser energy the protein undergoes direct coagulation while the vessels intima undergoes indirect thermal destruction, so that blood clotting is initiated. GYNECOLOGY removal of polyps, endometriosis treatment, vaginal rejuvenation, stress urinary incontinence treatment, laser coagulation of cervical erosion. Besides reactive collagen reduction in the tissue, reconstruction and neocollagenesis processes are initiated. The heated tissue grows in collagen, the fibers become shorter and thicker, which makes the affected tissue contract and strain. PHLEBOLOGY endovenous laser ablation, reticular varicosity. The destroying effect on the vessels endothelium comes through a thermal impact by laser emission. A laser carrying fiber gets introduced into a sore part of the vein through a centesis in the skin. The laser energy heats up the blood inside the vessel and makes it bubble-boil. These are the steam bubbles that bring the heat effect to the wall of the vein which directly damages the endothelium and coagulates the protein in it. ONYCHOMYCOSIS TREATMENT (nail fungus). The laser passes the nail plate, penetrates into the nail bed and thus heats up the fungus matter. The fungus clumps undergo high temperature impact and their growth stops. LASER LIPOLYSIS The treatment is ideal for effective reduction of pockets of fat such as love handles, upper back, double chins, and saddlebags. The laser probe breaks fat cells with thermal energy and provides for better separation of the fat from the neighboring tissue. 4

10 OCT is a unique device designed for noninvasive biological tissue diagnosis Sudoriparous gland Hair and sebaceous gland Optical coherence tomography (OCT) is a life-time method for biological tissues structure imaging. The method is referred to as optical biopsy owing to high image resolution (20-25 micron) and being an alternative to traditional excisional biopsy when the latter is not possible or undesirable in cases when no cell identification is required. It is best used for investing tissues study. The method is registered to be used in Russia (For life-time examination of skin morphology in health and disease by the optical coherence tomography method: Novel medical technology, 2008). Visualization occurs as a result of registration of probing emission (low intensity light, near infrared band, up to 1.5mW) radiating back from tissue elements, that come to feature different refractive index and re-radiation characteristics. OCT image is a 2D and 3D image of optical irregularities of the tissue at 1.5mm depth, in pseudocolor brown palette. It is aligned with the cross microscopic section. Principal OCT applications: ophthalmology, gynecology, surgery, carcinology, dentistry, angiology, urology, dermatology, and cosmetology. 10

11 Dermatology application: The method allows to acquire data related to morphological condition of healthy and pathologically modified skin in real time. OCT allows for visual differentiation of the epidermis and upper part of the dermis. The method is a tool to evaluate the condition of the dermo-epidermal junction area, dermis vessels, sebaceous and sudoriparous glands, hair follicle, all the ungual elements. OCT image of healthy human skin: Left - thin skin (forearm), right - thick skin (planta). 1 - superficial part of the horny layer with poorly cohesive scales, 2 - middle and lower part of the horny layer with adherent scales, 3 - superpapillary region of cell layers of the epidermis, 4 - interpenetrating area of epidermal excrescences and dermal papillae, 5 - upper part of the reticular layer of the dermis. The OCT visualizes major pathologic processes in dermis, and can be used for life-time diagnostic of dermatoses, inlcuding basal cell carcinoma, melanoma, differential diagnostic of melanomas and nevil, onychopathy. Spongiosis in eczema - vesicles Healthy skin OCT provides for multifocal and manifold examination which allows to monitor abnormal changes during cosmetic procedures and treatments to determine effect and find early signs of side effects (for instance, preclinical development of atrophia cutis during corticosteroid therapy). OCT images are interpreted via the following concepts: structural properties, layering, height, homogeneity, signal intensity within a layer, contrast of layers and areas with different signal intensity, boundary characteristics of layers and areas. ADVANTAGES OF APPLICATION: - noninvasive - imaging on-the-fly - multifocal and manifold examination, over-time examination - high spatial resolution and high image contrast - portable size, user friendly control, flexible probe, to be compatible with endoscopic gear.
